ISO 21527-1 Yeasts and Moulds Enumeration in Meat and Dairy
The ISO 21527 series of standards provides a comprehensive approach to the enumeration of yeasts and moulds, including those of the genus Candida, in meat and dairy products. This particular standard, part one (ISO 21527-1), focuses on the quantitative estimation of yeast cells and mold spores in these foodstuffs.
The importance of this testing is paramount for ensuring product safety and quality control in the dairy and meat industries. Yeasts and molds can contribute to spoilage, affecting shelf life, sensory properties, and ultimately consumer satisfaction. Accurate enumeration helps manufacturers comply with international regulatory requirements while enhancing their reputation through superior food safety practices.
The methodology outlined in ISO 21527-1 involves several key steps: preparation of the sample, inoculation onto selective media, incubation conditions, and final counting using colony-forming unit (CFU) techniques. The standard specifies precise protocols to minimize bias and ensure reproducibility among laboratories.
For dairy products, particularly cheese and yogurt, the presence of specific yeast species such as Candida lipolytica can impart desirable flavors but also poses risks if overgrown or contaminated with undesirable molds. In meat products like sausage and pâté, control measures are essential to prevent spoilage due to microbial growth.
The testing process typically starts by homogenizing the sample followed by dilution in buffered peptone water (BPW). Subsequently, serial dilutions are spread onto Rose Bengal Chloramphenicol Agar (RB-CA) plates for yeasts and Malt Extract Agar (MEA) for molds. Incubation at appropriate temperatures—30°C for 48 hours or 25°C for up to 7 days—is required before enumeration.
The results yield colony counts expressed as CFUs per gram or milliliter, which are reported alongside metadata such as incubation temperature and time. These data help assess compliance with national and international food safety standards like Codex Alimentarius and EU legislation.
Understanding the microbial flora in dairy and meat products is crucial for optimizing production processes, extending shelf life, and maintaining product quality. By adhering to ISO 21527-1, laboratories ensure accurate enumeration of yeasts and molds, thereby contributing significantly to food safety and consumer confidence.
